(No model.)Patented in England January 2, 1895, No. 144 3 in France July 25, 1895,No. 249,170 in Belgium July 25,1895,No.116,704; n Italy September30,1895, XXX, 39,439,1'XXVII, 227 ,in Spain October l2, 1895,1To. 17,785y in Austria November 21, 1895, No. L/4,406, and in India November23,1895,

To all whom it may concern:

Be it known that I, JOHN POYSER, a subject of the Queen of GreatBritain, residing at Mansfield, England, have invented new and usefulImprovements in Looms,(for which vpatents have been granted to me inGreat Britain, No. 144, dated January 2, 1895, and in India, No. 261,dated November 23, 1895, and to myself jointly with James Haywood andFrancis Edward Dyke Acland in France, No. 249,170, dated July 25,1895;in Belgium, No. 116,704, dated July 25, 1895; in Italy, Vol. XXX, No.39,439, Vol. LXXVII, No. 227, dated September 30, 1895; in Spain, No.17,785, dated October 12,1895, and in Austria, No. /4,406, datedNovember 2l, 1895,) of which the following is a specification.

This invention relates to looms for weaving and chieiiy to high-speedlooms of the kind described in the specification of former LettersPatent No. 547,130, dated Octoberl, 1895; and it consists in providingimproved means for operating the shuttle.

In the accompanying drawings, Figure 1 is a sectional front elevation ofone form of high-speed loom for weaving provided with my improved meansfor operating the shuttle. Figs. 2 and 3 are respectively a frontsectional elevation and a partial side sectional elevation of anotherform of high-speed loom provided with my improvements.

Similar referenceletters indicate corresponding parts throughout thedrawings.

According to the present invention a single picker-lever a, Figs. 1, 2,and 3, is provided pivoted to the base b of the loom and having a rollera (or projection) engaging in the groove of a cam c upon thedriving-shaft d, so that as the said shaft revolves the lever vibratesupon its pivot. To the upper-or free end of the picker-lever a arepivoted two radial pickers a2 a2, each of which is provided at its freeend with a roller a3, (or projection,) adapted to engage in a cam slotor groove a4, formed in the frame t' of the loom or in an independentplate attached to the loom. The pickers are each provided with a tootha5, projecting upward between the sides Z22 b2 of the shuttle-race andadapted to engage in a recess a6 in the shuttle e when the picker israised by the action of the camslot a4 upon the roller a3 (orprojection) and to be clear of the warp-threads when lowered by thesame, and the cam-slot a4 is sol arranged that the teeth of the pickersengage alternately with the shuttle, each picker being raised intoengagement before the other is lowered out of engagement, so that theshuttle is passed backward and forward through the shed in a positivemanner when the picker-lever is vibrated by the cam c.

Fig. 1 illustrates a loom having a curved shuttle-race, the curve beingthe arc of a circle described from the center of the pivot of thelevera, while Figs. 2 and 3 illustrate a loom having a straight shuttle-race.

Having now particularly described andascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. lIn combination, in a loom, the frame having acam-slot therein, the shuttle, the pivoted lever a with means foroscillating the same, a pair of pickers at the free end of the lever,each picker having a projecting tooth and guiding means consisting ofthe rollers and said cam-slot for giving the pickers with their teethmovement toward and from the shut-tlc, both of said pickers beingpivotally connected at one common point, to the free end of the rockinglever, one extending radially to the one side of the lever from itspivotal connection and the other extending radially in the oppositedirection from the pivotal connection, substantially as described.

2. In combination, in `a loom, the main swinging lever with operatingmeans therefor, a pair of pickers pivoted at the free end of the leverand swinging in the same plane with the oscillation of the main lever,the frame having the guiding -slot therein arranged laterally of andalong the face of the pivoted pickers and the rollers projectinglaterally from the pickers into the said guideslot, the said pickersextending radially from the free end of the swinging lever in oppositedirections.
